In some embodiments, the distance between the circle center of the upper energy absorption hole and the top of the top support is 1/4-1/3 of the height of the anti-rolling canopy frame of the cab, and the distance between the circle center of the upper energy absorption hole and the circle center of the lower energy absorption hole is 1.5-2.5 times of the diameter of the lower energy absorption hole.
In some embodiments, the diameter of the lower energy absorbing hole is no more than 1/2 of the width of the pillar.
In some embodiments, the uprights of the left and right sides of the top support are symmetrically arranged about the top support and are disposed proximate the rear side of the top support.
In some embodiments, the bottom of the upright post is provided with a hinge hole for connecting with a whole vehicle frame.
In some embodiments, the top support is in a herringbone configuration.
In some embodiments, the top supported left and right side rails are symmetrically disposed about the middle rail.
The utility model has the advantages that: the utility model discloses a design energy-absorbing hole structure on the stand of rack is turned over in the driver's cabin anti-roll, rationally match the driver's cabin anti-roll and turn over rack structural rigidity, have the energy-absorbing effect when guaranteeing the driver's cabin anti-roll and turn over rack structural rigidity, avoid the operation manipulator to bear too big load impact or warp and invade human safety limit living space when the whole car accident rolls over, better play the guard action of turning over, improve whole car security performance.

Detailed Description
The invention is further illustrated below with reference to the figures and examples.
The utility model provides a canopy frame is prevented rolling and turns over by driver's cabin with energy-absorbing structure, the canopy frame is prevented rolling and turns over by driver's cabin is whole L type casting structure, and it includes top sprag 1 and stand 2, and top sprag 1 is located the top of operation aircraft driver in the driver's cabin for keep out the heavy object impact at driver's cabin top, prevent to cause bodily injury to the operation aircraft driver. The upright post 2 is used for reasonably matching the structural rigidity of the cab anti-rolling shed frame, has an energy absorption effect while ensuring the structural rigidity of the cab anti-rolling shed frame, and is also used as a part for connecting the cab anti-rolling shed frame with the cab in addition.
In some embodiments, the top support 1 is in a zigzag structure, and as shown in fig. 3, the left cross beam 11 and the right cross beam 13 of the top support 1 are symmetrically arranged about the middle cross beam 12, and rounded corners or obtuse-angle-like rounded corners are adopted at the transition position of the casting structure.
In some embodiments, there are two columns 2, and the two columns 2 are respectively located at the left and right sides of the top support 1. The cab anti-rolling shed frame is fixed with the cab through the upright post 2. Specifically, the bottom of the upright post 2 is provided with a hinge hole 23 for connecting with the whole vehicle frame, and the upright post is connected with the vehicle frame by a pin shaft penetrating through the hinge hole 23.
The upright post 2 is provided with an upper energy absorption hole 21 and a lower energy absorption hole 22 positioned below the upper energy absorption hole 21, and the upper energy absorption hole 21 and the lower energy absorption hole 22 are through holes. The diameter of the lower energy-absorbing hole 22 is not smaller than that of the upper energy-absorbing hole 21, otherwise the influence effect on the structural rigidity is limited. Through design energy-absorbing pore structure on stand 2, have the energy-absorbing effect when guaranteeing the cab and prevent rolling the pergola structure rigidity intensity, avoid the manipulator to bear too big load impact or warp and invade human safety limit living space when the whole car accident rolls.
In some embodiments, in order to ensure the energy absorption effect, as shown in fig. 2, the distance between the circle center of the upper energy absorption hole 21 and the top of the top support 1 is 1/4 to 1/3 of the height H of the cab anti-rolling canopy frame, and the closer the energy absorption hole is to the top of the top support 1, the weaker the overall structure is.
In order to ensure the rigidity of the upright post 2, the distance between the circle center of the upper energy absorption hole 21 and the circle center of the lower energy absorption hole 22 is 1.5-2.5 times of the diameter of the lower energy absorption hole 22.
In some embodiments, as shown in fig. 2, the diameter of the lower energy absorbing hole 22 is not more than 1/2 of the width L of the pillar 2, so as to avoid the pillar structure from being too weak in rigidity, reduced in structural strength and too large in overall deformation.
Preferably, the distance between the circle center of the upper energy absorption hole 21 and the circle center of the lower energy absorption hole 22 is 2 times of the diameter of the lower energy absorption hole 22, and the diameter of the lower energy absorption hole 22 is 1/2 of the width of the pillar 2.
In some embodiments, in order to ensure the overall structural rigidity of the cab rollover protection shelf, the pillars 2 on the left and right sides of the roof support 1 are symmetrically arranged with respect to the roof support 1. Simultaneously stand 2 is close to the rear side setting of top support 1, avoids influencing the normal use of driver's cabin.
Because the unexpected direction of rolling of whole car is random, the utility model discloses a driver's cabin anti-roll all is provided with the energy-absorbing hole on the stand 2 of the left and right sides of rolling over the rack, the guard action that turns over that plays that can be better improves whole car security performance.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
